MAP 1540: Minimum Configuration
Notes:
1. Be sure to unplug the power cords before removing or installing processor card(s),
the memory card, or the system board to avoid damage to it.
2. This MAP assumes that a CD-ROM drive is installed and connected to the
integrated SCSI or IDE adapter, and a diagnostic CD-ROM is available.
3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM can load.
4. The term
″
POST indicators
″
refers to the icons (graphic display) or device
mnemonics (ASCII terminal) that appear during the power-on self-test (POST).
5. The service processor might have recorded one or more symptoms in its error log.
It is a good idea to examine that error log before proceeding (see “System
Information Menu” on page 196).
6. The service processor might have been set by the user to monitor server operations
and to attempt recoveries. You might want to disable these actions while you
diagnose and service the system. If you disable them, make notes of their current
settings so that you can restore them before you leave. The following settings may
be of interest to you.
Surveillance From the Service Processor Setup Menu, go to
the OS Surveillance Setup Menu and disable
surveillance.
Unattended Start Mode From the System Power Control Menu, disable
unattended start mode.
Reboot Policy From the System Power Control Menu, go to
the Reboot/Restart Policy Setup Menu and set:
a. Number of reboot attempts to 0 (zero)
b. Use OS-Defined restart policy to No
c. Enable supplemental restart policy to No.
Call Out From the Call-In/Call-Out Setup Menu, go to
the Serial Port Selection Menu and disable
call-out on both serial ports.
